Quantum Reports, 2022 We investigate the effect of time-dependent boundary conditions on the dynamics of a quantum bouncer—a particle falling in a homogeneous gravitational field on a moving mirror.

Gravitation Physics at BGPL [PDF]
, 2006 We report progress on a program of gravitational physics experiments using cryogenic torsion pendula undergoing large-amplitude torsion oscillation. This program includes tests of the gravitational inverse square law and of the weak equivalence principle.

Varying Constants, Gravitation and Cosmology [PDF]
Living Reviews in Relativity, 2010 Fundamental constants are a cornerstone of our physical laws. Any constant varying in space and/or time would reflect the existence of an almost massless field that couples to matter. This will induce a violation of the universality of free fall.

Performance and Flow Field of a Gravitation Vortex Type Water Turbine
, 2017 A gravitation vortex type water turbine, which mainly comprises a runner and a tank, generates electricity by introducing a flow of water into the tank and using the gravitation vortex generated when the water drains from the bottom of the tank.

Dark Energy as a Born-Infeld Gauge Interaction Violating the Equivalence Principle [PDF]
, 2006 We investigate the possibility that dark energy does not couple to gravitation in the same way than ordinary matter, yielding a violation of the weak and strong equivalence principles on cosmological scales.

The Motion of a Body in Newtonian Theories [PDF]
, 2010 A theorem due to Bob Geroch and Pong Soo Jang ["Motion of a Body in General Relativity." Journal of Mathematical Physics 16(1), (1975)] provides the sense in which the geodesic principle has the status of a theorem in General Relativity (GR).

The Effect of the Gravitation of the Moon on Frequency of Births
Environmental Health Insights, 2010 The purpose of this study was to examine the influence of the gravitation of the Moon on the frequency of births in Kyoto, Japan. A retrospective cohort analysis of 1007 consecutive births without the use of the induction agents was conducted on a ...

Matrix theory of gravitation [PDF]
, 2011 A new classical theory of gravitation within the framework of general relativity is presented. It is based on a matrix formulation of four-dimensional Riemann-spaces and uses no artificial fields or adjustable parameters.

Study of Anisotropic Fluid Distributed Hyperbolically in f(R,T,Q) Gravity
Universe, 2022 The core of this manuscript is to conduct a broad investigation into the features of static matter configurations with hyperbolical symmetry, which might possibly serve as formation of corresponding spacetime within the limits of f(R,T,Q) gravity, where (
